Math finds the best doughnut; the tactically enhanced coffee mug

The OPMOD Battle Mug is equipped with military-specification rails to mount its carry handle (from an AR-15) and any other gear (like the bucket o’ scopes they slapped on the one at the right). The idea of a “Battle Mug” is a little tongue-in-cheek, but OPMOD does actually make military-grade gun accessories, so you might want to leave some coffee in the pot if you see this mug headed your way.
